If you run into errors, please make sure to include the exceptions in the e-mail.
Verbal descriptions are sometimes hard to follow without having the code and the environment. You mean you take the same program and exchange the code line to use EmbeddedReadOnlyGraphDb ? Why do you do that? Why don't you create a second program that uses EmbeddedReadOnlyGraphDb, you can't do modifying operations anyway.
